On the terminal, the command does not complete (i.e. it does not return to the prompt), the fans on my laptop start whirring and the system gradually becomes unresponsive before my desktop crashes and the system becomes completely unresponsive. On both occasions I opened another window to run "top" to see what process was consuming resources but "top" never actually runs. On the second occasion I managed to run "dmesg" before the system crashed completely and saw multiple lines of text about a kernel oops and red-highlighted text about a null-pointer dereference. I could reboot with "Alt-PrtScr_REISUB". On reboot I was confronted with the "system problem detected" dialog, but selecting the "report" option didn't seem to do anything. I have 2 reports in /var/crash from the last oops which I will attach to this report. I cannot reproduce this on demand. Most of the time, wg-quick performs normally. On both occasions the laptop had recently woken from suspend, but invoking "wg-quick" after waking from suspend doesn't trigger it on demand. On the first occasion I was running with stock boot options. On the second, I was running with "mitigations=off" as an experiment. $ lsb_release -rd Description: Ubuntu 19.10 Release: 19.10 $ apt policy wireguard wireguard: Installed: 0.0.20190913-1ubuntu1 Candidate: 0.0.20190913-1ubuntu1 Version table: *** 0.0.20190913-1ubuntu1 500 500 http://gb.archive.ubuntu.com/ubuntu eoan/universe amd64 Packages 500 http://gb.archive.ubuntu.com/ubuntu eoan/universe i386 Packages 100 /var/lib/dpkg/status $ apt policy wireguard-tools wireguard-tools: Installed: 0.0.20190913-1ubuntu1 Candidate: 0.0.20190913-1ubuntu1 Version table: *** 0.0.20190913-1ubuntu1 500 500 http://gb.archive.ubuntu.com/ubuntu eoan/universe amd64 Packages 100 /var/lib/dpkg/status $ uname -a Linux padbeast 5.3.0-23-generic #25-Ubuntu SMP Tue Nov 12 09:22:33 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux # cat /etc/wireguard/wg0.conf [Interface] PrivateKey = MyPrivateKey= Address = 10.66.66.5/24,fd42:42:42::5/64 DNS = 8.8.8.8,1.1.1.1 [Peer] PublicKey = MyPublicKey= Endpoint = my.domain.com:1195 AllowedIPs = 0.0.0.0/0,::/0 I'm reporting this as a security bug due to the "Null pointer dereference" in the kernel, but don't know if that is relevant.
